' Claims. (Cl. 94-8) This invention relates to a transload device andmore particularly to such a device for use in pavement joints, concretehighways, airport runways and the like. Such a device is shown in myprior Patent No. 2,674,164, dated April 6, 1954. While the patent showntherein is satisfactory in operation it has the disadvantage of notbeing easily stacked for shipment in trucks which is the common way ofshipping transload devices.

It is therefore an object of my invention to provide a transload devicewhich is easily assembled and which can bearranged in nested positionfor shipment without danger of damage thereto.

This and other objects will be more apparent after referring to thefollowing specification and atached drawings, in which:

Figure l is a perspective view of an expansion joint assembly;

Figure 2 is a transverse section of the expansion joint of Figure 1;

Figure 3 is a view taken on the line III-III of Figure 1;

Figure 4 is an enlarged sectional'view of a detail;

Figure 5 is a view of a plurality of units stacked for shipment; and

Figure 6 is a view, similar to Figure 2, but showing a contractionjoint.

Referring more particularly to the drawings, reference numeral 2indicates a pair of concrete slabs having the usual filler member 4therebetween. My device may be made of two complementary units which aretelescoped together. Each unit has two longitudinal rods 6' and 8 spacedfrom the filler 4 and connected by rods 10 and 12. The lower end ofthe'rod 10 is welded to the bottom longitudinal rod 6 and 'extendsupwardly and outwardly therefrom andthen inwardly to form a knee 13.From the-knee 13 the rod 10 extends upwardly above the rod 8-towhich itis welded. The part of the rod 10 above the rod 8 is U-shaped, thusproviding an opening 14-for receiving a dowel 18 which iswelded to therods 8 and 10. The lower part of the rod 12 is shaped in the same manneras the rod 10, that is, it extends upwardly and outwardly from the rod 6to which it is welded and then inwardly to form a knee 19 and thenupwardly to the rod 8 to which it is welded. The upper part of the rod12 forms a clamping device 20 which is provided with a loop 22 forreceiving the free end of the dowel 18 and a longitudinal portion 24which extends along the rod 8. The free end of the portion 24 has a hook26 which is adapted to pass below and extend around the rod 8 to a pointjust below the axis of the rod. The rods 10 and 12 are arrangedalternately with the rods 10 of one unit being opposite rods 12 of theother unit. A plate 28 is welded to each of the dowels 18 on that sideof the filler 4 adjacent the rod 19. Plate 28 extends between the dowels18 and is provided with corrugations 30. Holes 32 are provided in theplate 28 between the dowels 18 for receiving the dowels of the otherunit. Holes 34 are provided in the filler 4 for passage of the dowels.The free ends of the dowels have a sleeve 36 2,834,266 Patented I May13,

telescoped thereover with an expansible filler 38 being provided in thesleeve 36 at the outer end thereof, as shown in Figure 4.

In assembly, the two units are brought together by passing the freeends'of the dowels through the openings 34 into the loops 22. Thesleeves 36 and fillers 38 are then applied to the dowels and the hook 26is moved from the dotted line'position of Figure 3 to the full lineposition, thus locking the two units together with the plates 2% bearingagainst opposite sides of the filler 4 to hold it in' position'whileconcrete is poured. The plates 28 do not interfere with the flow orpacking of the concrete around the dowels adjacent the joint, thusmaking it possible to provide dense concrete at the most criticalplaces.

The device functions in the usual manner as the concrete slabs 2 expandand contract.

In shipment the assembled units with the fillers 38 and sleeves 36removed are nested together as shown in Figure 5. As there shown thedowels 18 of the lowest unit are supported on woodenskids 40 which areof sufficient heightthat the unit is supported solely on the skids. Thelongitudinal rods 6 of the next unit are supported by the knees 13 and19. The height of the plates 23 is less than the vertical distancebetween the knees and the bottom longitudinal rod 6 so that the topparts of the plates of one unit are below the bottom of the plates ofthe next unit above.

Figure 6 shows my device as applied to a contraction joint. Thisjointdiffers from the expansion joint in that the plates 28, sleeves '36 andfiller 33 are omitted and a steel separating plate 42 is substituted forthe expansible filler 4. V

While several embodiments of my invention have been shown and describedit will be apparent that other adaptations and modifications may be madewithoutdeparting from the scope of the following claims.
